Hoya Australis Lisa: A Native Australian Fern

Hoya Australis Lisa

Hoya Australis Lisa is a native Australian fern that grows in the rainforest and is typically found in wet, shaded areas. It produces clusters of white flowers during the warmer months and has dark green leaves. Hoya Australis Lisa grows best in moist soil with plenty of organic material to keep it healthy. The plant also provides an excellent ground cover for gardens or yards because it will grow quickly and produce large amounts of shade.

Hoya Australis Lisa can be found in Queensland, New South Wales, Victoria, and Tasmania. It prefers moist conditions with high humidity levels. Hoya australis lisa likes to grow on rocks or tree trunks at an altitude of around 600 meters above sea leveland blooms from December to April every year.

Origin and description of Hoya Australis Lisa

Hoya Australis Lisa

Hoya Australis Lisa is an unusual hoya because unlike most Hoyas, this plant doesn’t climb up the support with twining leaf stalks but instead grows over the top of your surface, like a desk or table, for example, using its branch-like stems to hang down. The Hoya Australis Lisa blooms during the months of winter and spring. The flower is purple with a strong white throat that has orange spots on it.

The maximum height this vine may reach is about eight feet or two meters if it’s being grown indoors. If you want your Hoya Australis Lisa bush outside, make sure you put it in a partially shaded area.

Hoya Australis Lisa vines can be propagated by rooting cuttings taken from young stems, but make sure to take them in late summer or early autumn before new growth starts for best results.

While there are over 200 species of Hoya, the most commonly cultivated is a hybrid known as ‘Hoya Australis Lisa’. This hybrid was developed in Australia and is a cross between Hoya diversifolia and Hoya carnosa variegata (this plant has been lost). The name “Hoya” comes from the Hindustani word for “wax,” referring to the thick waxy cuticles of many Hoyas.

Hoya Australis Lisa propagation

Hoya Australis Lisa can be propagated by division of the rhizomes or root cuttings in spring or autumn after new growth has appeared. You can allow the cuttings to dry for a few days until they form callous, then press them into a well-draining potting mix.

Allowing some newly emerging leaves to remain on the stem will help provide energy for the plant during propagation. Keep moist but not soggy and place in indirect sun.

Some people use the rooting hormone, but this is not necessary.

General Care Information

Hoya Australis Lisa

Light requirements

The Hoya Australis Lisa plant prefers bright, indirect sunlight. If the leaves become dull or pale in color this could indicate that they are not getting enough light. The ideal situation would be to place them near a window where they can get sun during part of the day but are shaded from direct exposure. However, if you find it difficult to provide them with bright light, there is nothing to be worried about. Hoya plants are very hardy and can adapt quite well to lower levels of light as long as you’re sure they’re getting enough water.

There’s no need for most Hoyas (with the exception of hybrids) to be kept in direct sun all day long; just move them outside for a few hours on a nice, bright day and give them some shade the rest of the day.

Soil/potting mix

A good quality potting mix is the key to success. It should contain both moisture-holding material and drainage materials so that it can maintain adequate levels of water for uptake by plant roots, yet allow excess water to drain away. The soil mixture also needs a third ingredient – aeration – which provides an open structure that allows air penetration into the roots zone.


Water your Hoya Australis Lisa when the top of the soil is dry to touch. If you are growing indoors, place it near a window where there will be indirect sunlight. An easy way to tell if plants need water is by picking up one or two leaves between your thumb and forefinger either in the morning or evening time (when humidity levels are high) and if the leaves are dry, your plant needs water.


The best fertilizer for hoya australis lisa is one that is low in nitrogen. Hoya australis lisa does not thrive with fertilizers high in nitrogen since it will cause the plant to become leggy and weak, which is unhealthy for most hoyas. With this said, you can use any fertilizer as long as it has little or no nitrogen content.

If you do not know the contents of your fertilizer, I suggest using a general-purpose 20-20-20 fertilizer. This will be perfect for all your plants and will make sure they are getting everything they need to thrive.

For those who want to go one step further in providing nutrients for their hoya australis lisa, I suggest using a fertilizing schedule. The best time to fertilize your hoya australis lisa is in the spring and summer when it is growing most. However, if you want to do it all year round that’s fine as well.

The first thing on my fertilizer schedule for hoya australis lisa is once a month during the growing seasons. Then I suggest second fertilizing after your hoya australis lisa has finished blooming for that year.

By following these simple steps you can have a healthy, beautiful, and green hoya australis lisa!


Hoya Australis Lisa can grow in a wide range of temperatures. It prefers warm, humid conditions and will do well in the 70°F to 80°F (20°C – 25°C) range.


Hoya Australis Lisa prefers relatively high humidity. It will not do well in the 50% to 70% relative humidity range but thrives when it is around 85% RH.

They prefer humidity levels that are quite high; they do best when kept in an environment where their leaves can feel moist at all times. If you live in an area with low humidity (less than 40%) try misting your plant every day or placing it on a tray of wet pebbles to raise the humidity around it.

Pruning Hoya Australis Lisa

Hoya Australis Lisa

Prune Hoya Australis Lisa in the springtime, after it has flowered. Cut back overgrown vines and weak branches with small pruning snips or a sharp pair of shears. Remove all dead leaves from around the plant’s base to help promote healthy new growth. Do not cut off any green leaves, which will provide the plant with food.

If you are pruning Hoya Australis Lisa to help keep it under control or fit into an existing garden space, cut back long vines and branches so that they remain within reach for easy picking of the flowers. Cut off large leaves from areas of the vine where new growth is not desired, such as around the base of a tree or in an area where you want to encourage grass growth.

If you are pruning Hoya Australis Lisa because it is outgrowing its space and needs dividing, do so immediately after flowering has finished. Remove large leaves from areas of the plant that can be divided into separate plants without negatively affecting the rest of the plant.

Partially defoliate Hoya Australis Lisa to encourage flowering, especially in late spring and early summer. Remove a third or more of its large leaves from areas that do not need strong vine growth to keep them healthy and promote new blossoms. Leave only two or three small leaves on each stem.

When to repot or transplant

The best time to repot or transplant a Hoya Australis Lisa is in the Spring, but it can be done at any other time of year.

To repot or transplant a Hoya Australis Lisa, you need

  • A pot that will accommodate the roots of your plant
  • Potting soil made from peat moss and sand
  • Sharp knife for cutting away dead portions of the root system
  • Tweezers to remove small suckers on roots. You can also use your fingers.
  • Small, sharp scissors for cutting twine and the pot’s label (if needed)
  • You will also need a saucer to place underneath your Hoya Australis Lisa during transplanting so that you do not lose any of its precious moisture. You can buy these at garden centers or home improvement stores where they sell pots and containers.

Don’t water your Hoya Australis Lisa for at least a week after transplanting to give the roots time to adjust to their new environment. After this, you can resume normal watering practices until it is time for repotting again in Spring.


Hoyas often go dormant during dry periods of winter or summer, but it’s best not to let them completely dry out then! It might take weeks before the plant starts sending out new growth. For growing Hoyas indoors, you can tell that they are not dormant if there is still green in the leaves.

Flowers & Fragrance

The Hoya Australis Lisa produces small, white flowers with a pinkish-purple throat. The flower petals are cream-colored and have an orange-red bird’s eye center that is surrounded by the drooping lobes of the corolla.

The plant does not have a significant fragrance.

Growth rate

Hoya Australis Lisa grows quickly and requires a lot of room. In the right conditions, it can grow up to several feet each year! This means that you will need to trim your plant regularly if you want it to stay at a desirable size. If not done correctly, pruning this fast-growing vine could do more harm than good. It is best to trim it in the late winter months or early spring when new growth starts to emerge from the trunk of your plant.


Hoya australis, like many other species of hoya, is toxic to both people and pets. The toxicity level varies depending on the method of preparation (e.g., raw vs cooked), so it’s best not to eat or touch this plant without gloves. Hoya australis is also known to be toxic to livestock.

USDA Hardiness Zones

Hoya australis lisa is a native Australian plant that thrives outdoors in USDA growing zones eight through ten.

Pests and diseases

Hoya plants are susceptible to a number of pests and diseases. The most common pests that affect Hoyas include mealybugs, scale insects, thrips, aphids, and whiteflies. It’s also possible for your plant to have fungal or bacterial problems such as leaf spot or root rot if it is overwatered.

The most common diseases that affect Hoyas include leaf spot, root rot, and stem rot. Root rot is the result of overwatering or poor drainage whereas stem rot can be caused by cold temperatures or wet soil conditions during the winter months. If any of these problems are detected it’s important to remove the affected leaves or stems and repot your plant in fresh soil.
